ACTION:

SUMMARY:

This document announces that the EPA Administrator has responded to a citizen petition asking EPA to object to an operating permit issued by the Colorado Department of Public Health and Environment (CDPHE).

Pursuant to section 505(b)(2) of the Clean Air Act (Act or CAA), Petitioners may seek judicial review of those portions of the petition that EPA denied in the United States Court of Appeals for the appropriate circuit.

SUPPLEMENTARY INFORMATION:

The Act affords EPA a 45-day period to review and object to, as appropriate, a title V operating permit proposed by State permitting authorities. Section 505(b)(2) of the Act authorizes any person to petition the EPA Administrator, within 60 days after the expiration of this review period, to object to a title V operating permit if EPA has not done so. Petitions must be based only on objections to the permit that were raised with reasonable specificity during the public comment period provided by the State, unless the petitioner demonstrates that it was impracticable to raise these issues during the comment period or the grounds for the issues arose after this period. EPA received a petition from WildEarth Guardians dated February 26, 2010, requesting that EPA object to the issuance of the title V operating permit to Public Service Company of Colorado for the operation of the Pawnee Power Station. The Petition alleges that the Permit does not comply with 40 CFR Part 70 in that it fails to assure compliance with: (I) Prevention of Significant Deterioration (PSD) requirements; (II) particulate matter (PM) limits applicable to the coal-fired boiler; (III) other applicable PM emission limits (and fails to require the facility to sufficiently monitor fugitive PM emissions); (IV) the 20-percent opacity limit under the New Source Performance Standards, Subpart Y, which applies to coal unloaded to storage activities; (V) PM emission limits applicable to specified point sources (and fails to require the facility to sufficiently monitor PM from those point sources); (VI) CAA § 112(j) for air toxics; and (VII) PSD requirements in regard to carbon dioxide emissions.

On June 30, 2011, the Administrator issued an Administrative Order partially granting and partially denying the Petition. The Order explains the reasons behind EPA's conclusions.

Dated: July 13, 2011.

Stephen S. Tuber,

Acting Regional Administrator, Region 8.
